Reticulated polyamides and method of preparation

Abstract

Abstract RETICULATED POLYAMIDE COMPRISING DIVALENT RADICALS AND TRIVALENT RADICALS WHICH MAY BE ALIPHATIC OR AROMATIC RADICALS, SUBSTITUTED OR NOT, OR A PLURALITY OF AROMATIC RADICALS LINKED TOGETHER EITHER DIRECTLY OR BY AT LEAST ONE RADICAL SELECTED FROM THE GROUP COMPRISING THE ALKYL, DIOXY-ALKYL, CYCLANILIDENSES, -S-, -SO2-, -O-, -CO- RADICALS, THE DIVALENT RADICALS AND THE TRIVALENT RADICALS BEING LINKED TOGETHER BY THE STRUCTURE: -CO-NH-R3(-O-X)2-NH-CO- IN WHICH R3 REPRESENTS A TETRAVALENT RADICAL WHICH MAY BE AN AROMATIC RADICAL, SUBSTITUTED OR NOT, OR A NUMBER OF AROMATIC RADICALS LINKED TOGETHER DIRECTLY OR BY AT LEAST ONE RADICAL SELECTED FROM THE GROUP OF RADICALS RECITED ABOVE; X REPRESENTING A HYDROGEN OR AT LEAST ONE OF THE THREE RADICALS: R4, -CO-, AND -CO-R4 IN WHICH R4 REPRESENTS AN ALKYL OR ARYL RADICAL HAVING EACH OX GROUP FIXED DIRECTLY ON A CARBON ATOM OF THE TETRAVALENT RADICAL, IN THE ORTHO OR PERI POSITION WITH REPECT TO THE CARBON ATOM ON WHICH IS FIXED THE AMIDE GROUP -NH CO-, THE RATIO OF THE TRIVALENT RADICALS TO THE DIVALENT RADICALS BEING COMPRISED BETWEEN 1:20 AND 1:5. THE METHOD OF PREPARATION COMPRISES ESSENTIALLY THE REACTION OF ONE OF MORE DIAMINE COMPOUNDS WITH AT LEAST ONE COMPOUND OF DICARBOXYLIC ACID AND AT LEAST ONE COMPOUND OF TRICARBOXYLIC ACID.
